CHARLES MALDANER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO HANDLEBAR COMPANY, OF ILLINOIS.

HANDLE BAR SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 667,716, dated February12, 1901.

Application filed April 28, 1900. derial No. 14.706. (N motlel) T0 aZZw7t0m it may concern.-

Be it known that I, CHARLES MALDANER, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois,

have invented certain new and useful Improvements in Handle-BarSupporters, of which the following is a specification and which areillustrated in the accompanying drawings, forming a part thereof.

This invention relates to what are known in the trade as extensionhandle-bar supporters, in which there is a forwardly-projecting arm atthe upper end of the supporterstem, the handle-bar proper being securedat the forward end of such arm.

One object of the invention is to provide improved means for so securinga one-piece handle-bar to such an extension-support that it is capableof vertical adjustment independ- 2o ently of the vertical adjustment ofthe stem and admitting of the reversal of the handlebar.

A further object is to cheapen the cost of and simplify the manufactureof handle-bar supports of this type.

These objects are attained by the construction hereinafter fullydescribed, and which is shown in the accompanying drawings, in whichFigure 1 is a detail plan view of the handlebar supporter and a part ofthe handle-bar, some of the parts being broken away. Fig. 2 is avertical section of the supporter. Fig. 3 is a detail side elevation ofthe stem of the supporter and its projecting arm; and Fig. 4 is arearward elevation of the clamping-ring for holding the handle-bar, aportion of the handle-bar being shown in dotted lines.

The stem for entering the steering-head may have a body portion of anydesired form. As shown, it is tubular and slitted at its inner end, asshown at 12. An ordinary expanderplug 13 is located within the lower endof this stem, and a bolt 1a is provided for drawing the plug into thetube for the purpose of eX- panding it, so as to clamp it within thesteering-head, this bolt projecting through the upper end of the stem.

The stem 10 is provided at its upper end 0 with an integralforwardly-projecting arm 11.

The handlebar 12 is held within a split clamping-ring 16, which isprovided with a tangential stem 17, adapted to telescopically enter asuitable socket in the end of the arm 11. A screw-bolt 18 passes throughthe lips of the ring 16 and along the axis of the shank 17 and enters athreaded socket in the arm 11 at the base of its shank-receiving socket.The end of the arm 11 is transversely grooved, as shown at 19, and theshank 17 is provided with radially-projecting lugs 20 for entering thesegrooves. The shank maybe and preferably is provided at its base with ashoulder 21, adapted to abut against the end of the arm 11, the lugs 20projecting forwardly from such shoulder. The shank 17 having beeninserted within the socket of the arm 11 and the handle-bar being withinthe ring 16, the bolt 18 is turned up, at once securely and firmlydrawing the shank 17 into the socket of the arm and drawing the lips ofthe ring 16 together, so as to clamp the handle-bar. As shown, the ring16 extends downwardly from the arm 11. By loosening the bolt 18, so asto disengage the lugs 20 from the grooves 19, the handle-bar may beraised by simply turning the shank 17 upon its axis, so as to bring thering 16 above the arm.

The long bearing of the shank 17 within the socket for receiving itprevents any lateral movement and almost entirely supports the strain,so that there is comparatively little lateral strain upon the bolt 18.

I claim as my invention 1. In a handle-bar support, in combination, astem for entering a bicycle steering-head, an arm projecting forwardlyfrom such stem, a split clamping-ring for holding a handlebar and havinga tangential shank, the projecting arm of the stem being socketed toreceive the shank, and a screw-bolt passing through the shank and thelips of the ring and entering the projecting arm.

2. In a handle-bar support, in combination, a stem having aforwardly-projecting arm, a split clamping-ring for holding a handle-barand having a tangential shank, such shank telescopically entering theprojecting arm and being ad justabl y rotatable with reference thereto,and means for securing the shank in its adjusted position and forcompressing the clamping-ring.
